I'm sorry but I think you're out of luck. Camera Raw for Photoshop CS5 is limited to the 6.x series of Camera Raw. Newer Camera Raw releases (7.x, 8.x) only works with Photoshop CS6 as far as I know. Perhaps there will be an update to Camera Raw 6 but I wouldn't hold my breath. The last update was 6.7, for EOS 5D Mark III (and other cameras released around the same time).

I used Lightroom 5 for most of my image editing, but I also own Photoshop CS5. Lightroom is updated with the same functionality as found in Camera Raw for a lot less money than the upgrade to CS6 would cost me.

There is also the option of downloading the latest version of Adobe DNG Converter (free), which would enable you to convert your RAW images to DNG's which you could then open in Photoshop CS5. The RAW conversion in Camera Raw 7.x and Lightroom is a lot better than the old Camera Raw versions though, so you may lose some quality there.

I use BreezeSys Downloader and in there you can program a plug-in that calls the DNG converter while loading the raw files file the CF/SD cards, so for me the conversion will happen automatically. Then use Photoshop CS5 to process the DNG files and not the original Canon raw .CR2 files.

Try converting the Canon raw files using the Adobe DNG converter manually, then see how that works.

This is a business decision Adobe makes to "encourage" users to the next version of photoshop - All updates and support ceases on old versions the moment a new version is released, and any bugs you find can only be fixed by upgrading versions. Personally i think it's a p*** poor way of running a business, but that's what you get when a company has a virtual monopoly.

Perhaps we should be thankful that Adobe don't make cars, otherwise we'd need to buy a new car every time a tyre wears out...

Why would you upgrade to Win 7? It have been replaced with Win 8 a long time ago

I tend to think of the even numbered releases as "release candidates" for the odd numbered releases, not so much as replacements and definitely not as upgrades. Most of the world awaits Win 9 before they will retire Win 7.

What makes this camera differant than the 5D Mark ll or the 7D which I have used and can load into Photoshop? I'm a Nikon shooter using the D800 which also works in CS5 and a friend sold me his Canon 500 mm f/4 for a really great price so I went out and purchased the 70D now I'm thinking I should've bought the 7D.
